Fig. 7From: Control of multilayer biological networks and applied to target identification of complex diseasesIllustration of the minimum FVS union optimization problem in a multilayer network. Suppose that F1, F2 ,…, FN is the FVS in layer 1, layer 2, …, layer N respectively. The problem is converted to find the minimal union of F1, F2 ,…, FN, namely, minF1 ∪ F2 ∪  …  ∪ FNBack to article page
